With the advent of spring, you might find yourself staring into the abyss of your closet, wondering how on earth you're going to reinvent those faded Levi's and gladiator sandals...again. Since assembling a new warm-weather wardrobe is out of the question, we decided to go in search of new spring staples at some mass retailers you'd never expect to find them. Didn't think Sears or Old Navy had anything cool on offer? Think again, oh savvy bargain hunters. In fact, a real wardrobe upgrade starts here at just $3.99. Trust us: You won't believe what we've found.
